Extruded thermal insulation board, namely extruded polystyrene thermal insulation board, is a kind of foamed hard plastic board formed by heating and extrusion with polystyrene resin as raw material and other polymers added. Extruded sheet is a material that is continuously extruded and foamed by a special process. The hard film formed on its surface is even and flat, and the internal closed cell foam is continuous and uniform. It has a honeycomb structure. Therefore, it has the characteristics of high compression resistance, light weight, good waterproof performance, air impermeability, wear resistance and non degradation.
Extruded sheet is widely used in dry wall insulation, flat concrete roof and steel structure roof insulation, low-temperature storage ground, low-temperature floor auxiliary heating under heating pipe, parking platform, airport runway, expressway and other fields for moisture-proof insulation and ground frost heave control. It is a high-quality and low-cost heat insulation and moisture-proof material in the construction industry.

The general characteristics of extruded sheet are:
1、 Excellent and lasting thermal insulation
The lowest possible thermal conductivity is the goal of all thermal insulation materials. The extruded board is mainly made of polystyrene, which is originally an excellent low thermal conductivity raw material. With extrusion, the compact honeycomb structure can more effectively prevent heat conduction. The thermal conductivity of the shaped energy board is 0.028/mk, which has the characteristics of high thermal resistance and low linear expansion rate. The thermal conductivity is far lower than other insulation materials. Such as EPS board, foamed polyurethane, thermal insulation mortar, perlite, etc.
2、 Superior water resistance and moisture resistance
The extruded board has a tight closed cell structure, the polystyrene molecular structure itself does not absorb water, and there is no gap between the front and back sides of the board, so the water absorption is extremely low, and the moisture-proof and impermeability are excellent.
3、 Corrosion resistance and durability
General hard foam insulation materials are easy to age after several years of use, which will lead to water absorption and performance degradation. Because of its excellent anti-corrosion, anti-aging and thermal insulation properties, the extruded plate can still maintain its excellent performance under high water vapor pressure, and its service life can reach 30-40 years.
